The former football star Antonio Cassano, who competed for Real Madrid and Inter teams among the others, made an interesting comparison between tennis and football. Analyzing in an interview to Vanity Fair Cristiano Ronaldo's arrival at FC Juventus, Cassano said: 'Cristiano lacks nothing, let’s be clear, but that’s not the point. I love tennis. Now, Cristiano is like (Rafael) Nadal, a fantastic athlete built on talent, but also hard work and desire. (Lionel) Messi is more like (Roger) Federer. He is pure artistry and class. They are different, and you can prefer one to the other. I am with Messi, as he can make the difference even when standing still, he almost doesn’t need physical fitness.'
Cassano added: 'I love Messi, not as a counter-point to Cristiano, but because in my view he’s the best of all time and the emotions he gives me are unique. If I have to rationalise it or convince you, I ask you to find me someone else who handles the ball and scores so consistently as Messi.'
During Wimbledon, Federer compared his rivalry with Nadal than Messi and Ronaldo. 'They have a long-standing rivalry. I have the same with Rafa. They're very different from one another', the Swiss player said. 'I guess there are some similarities there as well. As similar as we are, Rafa and myself, we're still very different on many levels. I think it's pretty much the same for them. I never met them, so I can't really talk about how different or how similar they are to our rivalry. Obviously, in football, it's different because you're only as good as your team. The pitch is huge, with 11 of them running around. With us, we're a little more in control, let's be honest. I hope I can control it a bit better than they could. We'll see how it goes.'
